DRAW-BENCH.

SPECIFICATION forming part of Letters Patent N0.'580,715, dated April13, 1897. Application filed May 23,1896. Serial No. 592,861. (No model.)

To all whom it may concern:

Be it known that I, PAUL ERNST PRESCHLIN, a citizen of Switzerland,residing at 66 Broad StreetAvenue, in the city of London, England, haveinvented a new and useful Improvement in Draw-Benches, of which thefollowing is a specification.

This invention relates to means of supporting a tube, while it is beingdrawn through the die of a draw-bench, in correct line with the die. Forthis purpose about two feet above the draw-bench is fixed a railparallel to the bench, and on this rail there are arranged to runseveral carriages, in which are fitted vertical screws carrying at theirlower ends loops of wire or hooks, in which the tube rests. By turningthe screws in the one direction or the other the tube can be raised orlowered, so as to be adjusted accurately in line with the die. As thetube advances through the die the carriages and hangers advance with it.The draw-bench is preferably made double, so that two parallel tubes canbe drawn. In this case two parallel rails are provided, each having onit carriages. These rails are preferably fixed on the opposite ends ofcross-heads carried on supports which extend up from the middle of thebench between the two tubes.

Figure 1 of the accompanying drawings is a part side view, and Fig. 2 isa part plan, of a double draw-bench according to this invention. Fig. 3is an end View, and Fig. 4 is a transverse section on the line X X ofFigs. 1 and 2.

On an end frame A and on cross-heads 13, arranged at intervals along thedraw-bench, are fixed two girder-rails R, on which run several carriagesO, each carriage having wheels below as well as above the rail. On theouter side of each carriage there are eyes, through which passes avertically-sliding bolt D, its lower part being bent to form a hook Eand its upper part being screw-threaded to receive a nut F. On the hooksE are hung loops of wire G or other hangers, by which are suspended thetubes H. The rails R bein g parallel to the bench, on turning the nuts Fin the one direction or the other each of the tubes II can be accuratelyadjusted so as to have its axis in line with the center of the die,through which it is drawn in the usual way.

I make no claim, broadly, to a pipe or other carrier comprising asupport carried by a trolley and having means for vertical adj ustment.In my invention I carry the threaded bolts down upon the outside of therail and then bend their lower ends in and bring them under the rail, sothat the point of support for the weight will be in a straight linepassing vertically through the rail and wheels. The advantages of thisconstruction are obvious. 7

Having thus described the nature of this inventionand the best means Iknow for carrying the same into practical effect, what I claim is- Incombination with a draw-bench, a rail supported above and parallel toit, carriages thereon provided with vertically-adjustable threaded boltspassing downward upon the outer side of the rail and extending belowthe' same, their ends being curved, and brought beneath and in thevertical line of said rail and wheels of the carriages, to form hooksfrom which tube-supporting hangers aresuspended to support a tube in aline coincident with a vertical line passing through the rail andwheels, and adjusting-nuts upon the upper ends of the threaded boltswhich rise above the carriage, substantially as described. In testimonywhereof I have signed my name to this specification, in the presence oftwo subscribing witnesses, this 1st day of May, A. D. 1896.
